Abstract
In a display driver, one scanning period is divided into a period P and a subsequent period D. In the period P, a pre-charge voltage equal to an original data voltage is applied in a time-sharing manner to data lines in one block, and in the period D after the period P, the original data voltage is applied again.
Claims3
A display driver which applies a scanning voltage for setting a pixel to a selected state to a scanning line of a display panel in each one scanning period and applies a data voltage corresponding to a display data to a data line of the display panel, the display driver comprising:
- a circuit which applies the data voltage to a first data line connected to a first pixel among a red pixel, a green pixel and a blue pixel on the display panel in a first period of the one scanning period,
- applies the data voltage to a second data line connected to a second pixel among the red pixel, the green pixel and the blue pixel on the display panel in a second period of the one scanning period,
- applies the data voltage to a third data line connected to a third pixel among the red pixel, the green pixel and the blue pixel on the display panel in a third period of the one scanning period, and
- applies the data voltage to the second data line on the display panel in a fourth period of the one scanning period.
A display driver which applies a scanning voltage for setting a pixel to a selected state to a scanning line of a display panel in each one scanning period and applies a data voltage corresponding to a display data to a data line of the display panel, the display driver comprising:
- a circuit which applies the data voltage twice to a first data line connected to a first pixel among a red pixel, a green pixel and a blue pixel on the display panel in a first period of the one scanning period,
- applies the data voltage once to a second data line connected to a second pixel among the red pixel, the green pixel and the blue pixel on the display panel in a second period of the one scanning period, and
- applies the data voltage once to a third data line connected to a third pixel among the red pixel, the green pixel and the blue pixel on the display panel in the second period of the one scanning period.
